This is true.
for example, if line a has a slope of 1/2 then line b (which is perpendicular) has a slope of -2.
Answer:
-2x^2 - 27x -11

Answer:
probability = 0.503
Step-by-step explanation:
given data
now = 1:00 p.m
last ghost appearance = 12:35 p.m
solution
we consider here Ghost appearances occur in house according to a Poisson process having a rate = 1.4 ghosts per hour
so time duration from 1:00 pm to 1:30 pm = 0.30 min = 0.5 hrs
and we take random variable denoting inter-arrival time = Y
so here probability that the 7th ghost will appear before 1:30 p.m. is as
probability = P(Y < 0.5)
probability = 1 -
probability = 1 - 0.497
probability = 0.503

<h3>How to plot the function?</h3>
The function is given as:
h(x) = | -4, x < 3
| x + 5, x >= 3
The above function is a piecewise function.
It has 2 separate functions at two domains
This means that we plot the sub-functions in the piecewise function at their respective domain

The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
